Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet equipment, in particular to an anti-electric shock structure of a high-voltage power distribution cabinet. Background Art

[0002] A high-voltage distribution cabinet is an electrical product used for switching, controlling or protecting in power generation, transmission, distribution, energy conversion and consumption in power systems. It mainly includes high-voltage circuit breakers, high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switch cabinets. High-voltage distribution cabinets involve the complete assembly of primary and secondary equipment according to a certain wiring scheme, and have functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and busbar connections.

[0003] After searching, the anti-electric shock structure of the high-voltage distribution cabinet disclosed in the Chinese patent with publication number CN216750661U is aimed at improving the structure of the existing high-voltage distribution cabinet. During installation and maintenance, the high-voltage distribution cabinet can be divided into two parts. The operator no longer needs to extend his arms into the interior of the high-voltage distribution cabinet, which removes the constraints of the side panels of the high-voltage distribution cabinet, facilitates the installation and maintenance of the operator, and avoids the risk of accidental electric shock. However, it does not solve the problem of connection confusion and loose fixation. Therefore, the induction light can be used to determine whether there is leakage. The fixing block and the protective shell respectively protect the connector and the wiring harness to avoid contact between adjacent wiring harnesses, causing circuit confusion and causing short circuit or equipment damage.

[0004] There are still some shortcomings in the use of the above-mentioned high-voltage distribution cabinet. During the daily operation of the high-voltage distribution cabinet, the distribution cabinet is usually placed at a position close to the ground. When water accumulates on the ground due to rain or other environmental factors such as human factors, it is easy for the accumulated water to penetrate into the high-voltage distribution cabinet due to the close distance between the accumulated water and the distribution cabinet, causing the internal lines to short-circuit due to water, which can easily cause the safety risk of electric shock and reduce the safety factor during the use of the distribution cabinet.
